In January 2022, we launched Amazon EC2 Hpc6a cases for purchasers to effectively run their compute-bound excessive efficiency computing (HPC) workloads on AWS with as much as 65 % higher value efficiency over comparable x86-based compute-optimized cases.
As their jobs develop extra complicated, clients have requested for extra cores with extra compute efficiency and extra reminiscence and community efficiency to cut back the time to finish jobs. Additionally, as clients look to carry extra of their HPC workloads to EC2, they’ve requested how we are able to make it simpler to distribute processes to make the very best use of reminiscence and community bandwidth, to align with their workload necessities.
Today, we’re asserting the overall availability of Amazon EC2 Hpc7a cases, the subsequent era of occasion sorts which might be purpose-built for tightly coupled HPC workloads. Hpc7a cases powered by the 4th Gen AMD EPYC processors (Genoa) ship as much as 2.5 occasions higher efficiency in comparison with Hpc6a cases. These cases provide 300 Gbps Elastic Fabric Adapter (EFA) bandwidth powered by the AWS Nitro System, for quick and low-latency internode communications.
Hpc7a cases characteristic Double Data Rate 5 (DDR5) reminiscence, which gives 50 % larger reminiscence bandwidth in comparison with DDR4 reminiscence to allow high-speed entry to knowledge in reminiscence. These cases are perfect for compute-intensive, latency-sensitive workloads resembling computational fluid dynamics (CFD) and numerical climate prediction (NWP).
If you might be operating on Hpc6a, you need to use Hpc7a cases and make the most of the two occasions larger core density, 2.1 occasions larger efficient reminiscence bandwidth, and three occasions larger community bandwidth to decrease the time wanted to finish jobs in comparison with Hpc6a cases.
Here’s a fast infographic that exhibits you the way the Hpc7a cases and the 4th Gen AMD EPYC processor (Genoa) evaluate to the earlier cases and processor:
Hpc7a cases characteristic sizes of as much as 192 cores of the AMD EPYC processors CPUs with 768 GiB RAM. Here are the detailed specs:
| Instance Name | CPUs | RAM (Gib) |
EFA Network Bandwidth (Gbps) |
Attached Storage |
| Hpc7a.12xlarge | 24 | 768 | Up to 300 | EBS Only |
| Hpc7a.24xlarge | 48 | 768 | Up to 300 | EBS Only |
| Hpc7a.48xlarge | 96 | 768 | Up to 300 | EBS Only |
| Hpc7a.96xlarge | 192 | 768 | Up to 300 | EBS Only |
These cases present larger compute, reminiscence, and community efficiency to run probably the most compute-intensive workloads, resembling CFD, climate forecasting, molecular dynamics, and computational chemistry on AWS.
Similar to EC2 Hpc7g cases launched a month earlier, we’re providing smaller occasion sizes that makes it simpler for purchasers to choose a smaller variety of CPU cores to activate whereas maintaining all different assets fixed based mostly on their workload necessities. For HPC workloads, frequent situations embody offering extra reminiscence bandwidth per core for CFD workloads, allocating fewer cores in license-bound situations, and supporting extra reminiscence per core. To be taught extra, see Instance sizes within the Amazon EC2 Hpc7 household – a distinct expertise within the AWS HPC Blog.
As with Hpc6a cases, you need to use the Hpc7a occasion to run your largest and most complicated HPC simulations on EC2 and optimize for price and efficiency. You may use the brand new Hpc7a cases with AWS Batch and AWS ParallelCluster to simplify workload submission and cluster creation. You may use Amazon FSx for Lustre for submillisecond latencies and as much as lots of of gigabytes per second of throughput for storage.
To obtain the very best efficiency for HPC workloads, these cases have Simultaneous Multithreading (SMT) disabled, they’re obtainable in a single Availability Zone, they usually have restricted exterior community and EBS bandwidth.
Now Available
Amazon EC2 Hpc7a cases can be found at present in three AWS Regions: US East (Ohio), EU (Ireland), and US GovCloud for buy in On-Demand, Reserved Instances, and Savings Plans. For extra data, see the Amazon EC2 pricing web page.
